Can't make a recommendation without knowing the pedal ratio and whether power or no.

yeah, I gotta learn to read the header. If it were me I'd stay with the 1 1/32". If you run out of pedal you'll be forced to go to a 1 1/8".

do you think I need to upgrade to a willwood master cylinder vs the smaller MC of the old mopar?  The volume of the wildwood is greater than the old mopar does that make a difference?

6 piston front with 4 piston rears will require the 1 1/8 bore unless you have fabricated a custom linkage.
